title: The neural generation of a unified illusion in human vision.
abstract: The neural mechanisms of visual binding in humans were investigated by measuring the brain's high-frequency electric responses (36-44 Hz) to the subjective visual perception of a unified three-dimensional illusion. 40 Hz synchronization was found over occipital and right parieto-temporal areas 500-300 ms before visual awareness of the three-dimensional Gestalt was reported, but not during the viewing of the illusion. At lower frequency bands (8-13 Hz and 13-20 Hz) no corresponding synchronization was found. 40 Hz synchronization thus directly correlates with the construction and emergence of a unified visual percept and may reflect the rapid formation of transient functional connections between spatially separated cortical areas.
